Flip flop hub= (in most cases) a hub with a freewheel side and a side with threading for a cog and lockring. The cog screws on one way, the lockring threads on the opposite way. This is so backpressure on the pedals doesn't translate into the cog coming loose.

Please do yourself a favor and go over to http://www.sheldonbrown.com/ and read every single thing on the website.

More importantly, find yourself someone to ride with- someone with a ton of experience on a bike- and just listen to them. If you can't find this person easily, go to a co-op and learn, learn, learn.
